How to instantiate an array of Map<Integer, Double> ?
I'm trying to convert legacy code to use generics.
Old data structure:
Hashtable positions[] = new Hashtable[n];
New (unsuccessful...) attempt:
Map<String, Double> positions[] = new HashMap<String, Double>()[n];
Can't get this to compile, no matter what permutation I try of <> and ().
Can someone please explain how to do it?
Thanks,

Unfortunately this will not work. There are limitations when declaring generic arrays that mean you have to do something like -
Map<String, Double>[] positions = (Map<String, Double>[]) new HashMap[10];
Not very nice but ...
